IMPROVEMENT IN APPARATUS FOR CARBURETING AIR.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that L'HENRY ALBRTUHAPIN, of

the city, county, and State of New York, have invented a new and, useful Improvement in Carbureting Apparatus, of which the following is a full, clear,

and exact description, reference being ,had to the accompanying drawing forming part of this specification, and which represents a sectional elevation of a Y carbureting apparatusihaviug myI improvement ap-l plied to it.- A

My Invention, which is mainly designed for the carburetlng of street-gas, consists in a novel construction 'of the carbureting apparatus, whereby all the tubes or connections for filling and drawing off the carbureting liquid, and otherattaehment-s connected-with thev supply of said liquid from the carbureting reservoir to the carburetiug-chamber, but more especially the reg'- ulating-valve forcoutrolling the discharge from the reservoir to said chamber, are in communication with and accessible from a chamberv arranged above the tank or reservoir, and which is under cover of a sealed lid. This dispenses with all break in the side or through the walls of the apparatus, and reduces. the

risk ot' accident by leakage, also retains any escaping vapor within the apparatus proper, and, on removal of the sealed lid, exposes the several'connections, hereinbefore referred to, for the purposes of inspection and adjustment or repair as required. f

The invention also consists in a combination, with the pipe which carries off' the carbureted gas from the apparatus, of a pipe or connection fitted with a cock or valve, and establishing communication between said gas-pipe and an air-escape pipe or opening in the upper portion of the tank, whereby any condensed air and vapor with which it may be charged, produced in filling the tank, may be discharged into the gas-pipe.

The invention also comprises, in combination with an outer water or safety-jacket, an interposed air-circulating chamber between said jacket and the carbureter proper, which it incloses, said chamber essentially diiering from a confined air-space by b ein g provided with suitable openings or ducts to provide for a free circulation of air through it, and for carrying oi as rapidly as formed any vapor leaking into said chamber, or otherwise avoiding any excessive and danger'- ous accumulation of vapor therein.

Referring to the accompanying ,drawing- A represents the tank or reservoir ofthe apparatus, into which the carbureting liquid is entered and drawn oli' therefrom, or surplus and refuse removed as required, by means of a tube, l), arranged to project thrpugh the top of the tank down to nearly the bottom thereof.

To effect the filling of the tank A, an air-escape or vacuum-tube, c, may also be used, the same being likewise arranged to project through the top ofthe tank,` but only entering to a limited distance down within it. These tubesb and c may be provided withsuitable cocks orvalves on their exterior or upper projecting ends, and be connected, respectively, by supplementary pipes, with a dip-pipe and pump attached toorforming part of a lling-can, so that the pump may first be worked to produce a vacuum within the tank A, and 'afterward to force the liquid from the can into the tank. This provides for the charging `of the 'tank in a rapid manner, and from a level which is considerably below the tank, also for-the drawing off of the 4liquid or refuse, when required. Any other filling and drawingioif means, however, may be employed, and in some cases the tube c be dispensed with, or when used,v instead of :operating as a vacuum-pipe in connection with a'pump, it may, under a different mode of filling, be employed as an escape-pipefoicondensed air produced in the upper portion of' the tank during the process of filling.

ln such case I connect such tube c, as by a pipe or connection, ni, litted with a 'cock orvalve, with the lpipe c which carrieswoi ythe carburete'd gas into the building. By this connection m ailcondensed air and vapor with which it may be charged is passed off Into the pipe e for use along with the gas.

B is the carbureting-chamber, andtl the gas-inlet pipe, which latter, together with the gas-outlet pipe e, is likewise preferably disposed to run up through the tank A.

Projecting up said tank are also the draw-oli' pipe-` f, from the carbureting-chamber B,4 and the supplytube g thereto, and connection by which the regulating-valve h is operated to control the supply of liquid from the ,tank A to the carbureting-chamber.

I is a float-indicator for ascertaining the level of the liquid in the tank. v

Said indicator, like the tubes b and c, the draw-off pipe f from the carbureting-chamber B, and the regul exterior, is an important feature in this invention, inf

asnluch as it reduces the liability of leakage, while the connection ofthe same and ofthe filling and drawingoff attachments and indicator, all within the chamber C, under cover of the sealed lid, as described, not only retain vapor leaking past said attachments or connecs tions within the carbureter proper', but provide for a -ready accessibility 'to said connections by .simply removing the sealed lid D. l

E is a safety water-jacket or chamber surrounding the whole structure, and li an interposed air-circulating chamber` or space between said Water-jacket and the carbureter proper, to form an additional safe-guard.

This air-chamber insnlates, as it were, the carbn-4 refer, being arranged around its sides and bottom or bottom and top, and the water-jacket E similarly insnlates said air-chamber, which latter is provided with vents or pipes k k that, in connection with an 0pen' ing, l, made in the top of the water-case, serve to keep up a circulation of air Within the chamberl F, which provides for the carrying oit-of an y. liquid oryapor that 4might escape from the carbureter into said chamber, instead of allowing it to accumulate for mixture with a fixed. supply ofair till a dangerous orA explosive condition was reached.

y What is here claimed, and desired to be secured b y Letters Patent, is-

i 1. The arrangement, relatively withv the tank A, of .the chamber-'0, provided with a sealed lid or coer, as

supply from the tank tothe carbureting-chambe-r is regulated and made capable of operation from within the sealed upper chamber O, substantially as specified.

2. The arrangement, relatively with the sealed upper chamber, ot' the several pipesor connections by which the liquid. is' .supplied to and drawn fromthe herein set forth.

cape tube 0, of the connection fm, substantially as and for the purpose herein'described.

bureter and with an outer water-case or jacket E', of an air-circulating space or chamber F, provided with `vents or ducts, substantially as and for the purpose or purposes specified.
